Echoflex Installation Guide
Access Interface
EchoConnect
The Interface connects to the EchoConnect station communication bus.
EchoConnect is a bi-directional protocol that uses one pair of wires
(data + and data -) for both data and power. Echoflex recommends using
Belden 8471 Class 2 wire (or approved equal – see the Echoflex cable
cross database
echoflexsolutions.com/files/Elaho_Data_Cable_Wire_
for equal alternatives). The total combined length of an
EchoConnect wire run using Belden 8471 may not exceed 500 m
(1,640 ft), with a maximum distance of 400 m (1,312 ft) between any two
devices.
Note:
All control wiring should be installed and terminated by a
qualified installer and should follow standard wiring installation
practices. Leave approximately 25.4 cm (10 in) of wiring in the
back box for connection and to allow slack for future service
needs.
Note:
Echoflex requires that all stations and devices be grounded
for ESD protection. Pull an additional 2.5 mm
2
(14 AWG) wire for
grounding when control wires are not installed in grounded metal
conduit.
Prepare for installation
The ElahoAccess Interface ships with the electronics, wall plate, and
wire termination kits including wire pigtails for 24 VDC auxiliary
power and EchoConnect.
The station may be installed into an industry-standard flush-mount back
box (RACO 690 or equivalent provided by others) or surface-mount back
box (sold separately and available from Echoflex).
Installation
The back box must be installed plumb and square for best results. Ensure
the back box is clean and free of obstructions and that all wiring is
installed correctly.
Locate the wire termination supplies included with the packaging.
